  • Route consistency checker for network devices
    Patent number: 11165684
    Abstract: In general, this disclosure describes a network device that checks consistency between routing objects in a routing information base (RIB), a forwarding information base (FIB), and packet forwarding engine (PFE) forwarding tables. A method includes generating a marker that causes a routing protocol daemon, a control plane kernel, and PFEs of a network device to calculate zonal checksums for a plurality of zones using consistency values for each routing object within a RIB, a FIB, and corresponding forwarding tables respectively. The method includes performing a consistency check on the RIB, the FIB, and the forwarding tables to determine whether the routing objects in each of the RIB, the FIB, and the forwarding tables are consistent with each other. The method includes, when the RIB, the FIB, and the forwarding tables are not consistent, performing an action related to at least one of RIB, the FIB, or the forwarding tables.
